在远东地区，欧亚大陆和日本海对岸的日本列岛之间的鸟类谱系呈现出一种共同的分化模式。Buteo burmanicus和Buteo japonicus通常被认为是更新世在远东地区分化的东方鹫的一对亚种。然而，它们分化的背景仍然未知，因为它们的分类模糊性使研究人员无法比较它们的迁移路线，分布范围和其他特征。在这里，我们调查的迁移路线和分布范围的遗传鉴定的两个亚种的差异。我们根据线粒体DNA序列鉴定了28个缅甸亚种和日本亚种，并利用GPS跟踪装置追踪了它们从日本迁移的情况。结果表明：（1）B. j. burmanicus在日本西部越冬;其次，B. j. burmanicus迁移到欧亚大陆，沿着大陆东部海岸向北迁移，而B. j. japonicus则在日本列岛内迁移。最后，缅甸亚种的夏季活动范围与缅甸亚种的夏季活动范围不重叠。研究结果表明，缅甸和日本的迁飞方向和繁殖范围沿着日本海划分。我们推断，日本海的存在以及飙升的猛禽避免穿越大型冷水体的迁移行为可能阻止了它们之间的基因流动，并导致了日本列岛的B. j. japonicus的特有性。
In the Far East, multiple avian lineages show a common divergence pattern between the Eurasian continent and the Japanese Archipelago across the Sea of Japan.Buteo japonicus burmanicusandButeo japonicus japonicusare often regarded as a pair of subspecies of the Eastern Buzzard that differentiated in the Far East during the Pleistocene. However, the background to their differentiation remains unknown because their taxonomic ambiguity prevents researchers from comparing their migration routes, distribution ranges and other characteristics. Here, we investigated differences in the migration routes and distribution ranges of the two genetically identified subspecies. We identified 28B. j. burmanicusandB. j. japonicusindividuals based on their mitochondrial DNA sequences and tracked their migration from Japan using GPS tracking devices. Three key results were found. First,B. j. burmanicuswintered in western Japan. Second,B. j. burmanicusmigrated to the Eurasian continent and flew north along the eastern coast of the continent, whereasB. j. japonicusmigrated within the Japanese Archipelago. Lastly, the summering range ofB. j. burmanicusdid not overlap with that ofB. j. japonicus. Our results suggest that the migratory directions and breeding ranges ofB. j. burmanicusandB. j. japonicusare divided along the Sea of Japan. We inferred that the presence of the Sea of Japan and the migratory behaviour of soaring raptors to avoid crossing a large, cold‐water body may have prevented gene flow between them and caused endemism ofB. j. japonicusin the Japanese Archipelago.
